The Camaro had a significant change in the Z28 engine lineup: the LU5 Crossfire 305 V8 was supplemented in April 1983 by an all-new 5.0 L L69 4 bbl 190 hp (142 kW) High-Output (HO) V8. This engine was only available with a manual transmission in 1983. Due to its late introduction, only 3,223 L69 V8s were sold for the 1983 model year.
